Year after year, the thermal dissipation due to power electronics, among other causes, has been increasing. As the demand for highly efficient cooling systems is correspondingly growing, the classical systems are becoming outdated. In that context, Capillary Pumped Loops may be envisioned as innovative and efficient heat transfer devices, but the data concerning their operation characteristics for terrestrial applications remains scarce. The purpose of this study is to develop a reliable steady state modeling tool for these devices as they function under gravity field. CPL modeling uses a nodal method with ESACAP software that leads to easier integration in global system modeling. The experimental setup used for validation is a "Capillary Pumped Loop for Integrated Power" (CPLIP) with a test bench available at the PPRIME institute. After comparison between modeling and experimental results, some parametric studies will be presented.
